Steps to reproduce:

  1. Edit a duplicate question and attempt to add the same question as a second duplicate.

Expected behavior:

I should see an error telling me I can't add a question as a duplicate twice.

Actual Behavior:

I can't see the error alert/modal, it's hidden by the dupe picker.

There seems to be regression on this bug. I just reproduced this again today.

z-index indeed. Looks like something changed with z-indexes between when I originally wrote the error popup code to when this got released.

Fixed in the next build.
